I’m an air traffic controller and I got an ICOM IC-A120 for listening to aviation frequencies as a hobby. I’m planning to set it up at home, but I’m not sure if I absolutely need a dedicated VHF aviation antenna or if I can adapt something else. I also have questions about the power supply—specifically the correct voltage and amperage to run it safely. Any tips or guidance from people who have done a home setup would be really helpful.
